Hi Hi , I can move color in the box but the result seems like opposite with the result of Chili

Hmm... Can you specify the problem? I'm kinda lazy.

Looks cool for sure.

Code: Select all

void Game::ComposeFrame()
{
	int y = boxY;  // dividing int's where the result is less than 1 but greater than 0 will return 0
                           //  if you want a decimal use float instead of int

   while( y < boxY + boxWidth )
   {
      int x = boxX;   // if you change the int y to float y you might want to do the same here.

      while( x < boxX + boxWidth )
      { 
		  if (x/b==y/b)
          //  It didn't seem to make a difference, but you forgot the { } 
                          gfx.PutPixel( x,y,(x+50)*b/2/(y+50)*2,(y+50)/(x+50)*b+100,(y+50)*(x+50)/2/b);
		  else
         // again missing the { }
			  gfx.PutPixel(x,y,x+b,b-y,max(x,y));
                  x++;
      }
      y++;
   }
	// adjust the size of the box
	if( kbd.SpaceIsPressed() )
	{
                // missing the { } and b never changes, b = 400 the entire program so this code 
                // never gets executed.
		if ( b<3 || b>800)f*=-1;
		b+= f*2;
	}

	if( kbd.EnterIsPressed() )
	{
		boxWidth = boxWidth + 3;
	}
	
	// move the box
	if( kbd.RightIsPressed() )
	{
		boxX = boxX + 3;
	}

	if( kbd.LeftIsPressed() ) 
	{
		boxX = boxX - 3;
	}

	if( kbd.UpIsPressed() )
	{
		boxY = boxY - 3;
	}

	if( kbd.DownIsPressed() )
	{
		boxY = boxY + 3;
	}
	
	
}

not sure if it was your intention, but the window height is only 600 (0 - 599) so

Code: Select all

 
 while( y < boxY + boxWidth )

will make the box draw off the bottom of the screen, I'm not sure why there wasn't an error from drawing off the screen.

Left half is what is displayed with x and y being int and right half is x and y being float.
